At recent trials held in London's Docklands and the Firth of Forth, WFS showed how the technology can be used to monitor coastal erosion or act as an early warning system in the event of emergencies, such as pollution incidents.

The Livingston-based company, which specialises in underwater communication and navigation technology, successfully transmitted live data from sensors on the seabed through water to a terminal onshore.

Through-water and through-ground wireless technology is also generating international interest from the oil and gas exploration industry.

To meet demand, WFS recently opened new offices in Houston, Texas and Washington D.C.

The senior management team is currently exploring the best way to reach new international markets from their base in Scotland.

Brendan Hyland, chairman and founder of WFS, said: "Our technology opens up new frontiers for environmental monitoring by making it easier and safer to monitor and explore the seabed.
